This listing comes with a set of 7 tuning forks and a velvet carrying pouch.
The brain is always active with measurable electric impulses. There are five measurable brain wave states. Each state is associated with different states of consciousness and different levels of activity.
These tuning were created with a process called Brain Entrainment in mind. The idea is that the brain can be trained to synchronize with these desired states by activating the corresponding frequency either with single Hz frequencies or by using binaural beats (the use of two fundamental frequencies to create a third, desired frequency, the difference between them).
This set includes the following tuning forks:
Gamma (use by itself) - Highest Activity State Beta - High Activity Alpha - Relaxed, Focused State Theta - Meditative or Dream State Delta - Deep Sleep State Fundamental - To be used with Beta, Alpha, Theta, and Delta Forks
